How often does your cable company release
updates/fixes/firmwares for the box ? This is not
acceptable, and further, seems illegal - if the letter
of the law is to mandate the existence of these ports
and thus and such abilities on those ports, then
having them refuse playback/record is a breach of that
I would call them and point out that unlike other
"technical difficulties", this one puts them in breach
of the law, and then threaten to report them to the
FCC over it.

Ok, this is absurd. Sorry, but the IR blasting method
that everyone is using with their tivos and their
HTPCs, etc., is completely lame. It's a duct tape
style hack that I will not be using.
Do you have any idea what the difficulty is ? Is it
possible, but just disabled in that particular box ?
Or does that box not even have that ability ? It
seems that other (non myth) people (not with time
warner) are changing channels with that box over
What advantage do the cable companies gain by not
allowing channel changing over firewire ? What do
they gain ?
